PC Implementation - Work in groups of 2
- Start with this simulation model of the 4 microphones. Extract to your Home Directory and run MicSourceLocator.vi. This can be the starting point for your application.
- Source Localization
- Compute angle of arrival for each pair
- Compute source location by computing the intersection of the 2 lines given (x,y,theta) of each pair
- Compute all possible intersections (Web)
- Bandpass signal on all channels
- Spectrogram
- Store previous buffer and do level detection to handly an Asynchronous Source
- Source Localization
- Test with microphone array microphone array. Connect the line out from the PC to a speaker and generate a chirp on the sound card using Chirp2SoundCard.vi.
- If it doesn't work, you can use these waveforms to troubleshoot.
Robot Implementation - Work in groups of 2
Projects for smaller groups:
- Compute angle of arrival on Robot platform
- PC to Robot communication using Shared Variable
- Robot position control (x,y,theta)
- Main PC Controller to compute source location from 5 robots
- Manual Position
- Automated controller
- Robot/FPGA implementation of Cross Correlation
- Thin client communication to Robot
System Integration - Everybody
- Get all of the individual pieces to work together on all 5 robots
